"Waiting for a sunny day to conduct tests", "guessing the spectrum based on experience", and "controlling the light efficiency by luck" - not long ago, these reluctant choices were the norm in fields such as photovoltaic, aerospace, scientific research, and agriculture when facing natural light. The "uncontrollability" of natural sunlight is like an invisible wall, hindering the innovative steps of countless practitioners. With 20 years of accumulation in optoelectronic technology as its foundation, Saifan Optoelectronics has developed a solar simulator that features "precise replication, stable output, and flexible customization". It has transformed into a "wall-breaking leader" of light, using a beam of "controllable, malleable, and customizable" light to break through innovation bottlenecks for various industries and make "active control of light" a reality.
Photovoltaic research and development: Breaking the "Waiting Curse" with "Precise Light" to Accelerate the development of High-efficiency batteries all the way
For half a month, it has been raining continuously. The test data of perovskite solar cells has been like a "headless fly". After a long wait for the sunny day, the efficiency measured in the morning was 23.2%, but it dropped to 21.5% in the afternoon, completely disrupting the research and development plan. The complaint of the R&D manager of a certain photovoltaic enterprise has pointed out the pain points of the industry. The "fickleness" of natural light has put the research and development of high-efficiency batteries in a passive situation of "relying on the weather". It was not until the arrival of the Saifan solar simulator that this curse was completely broken.
As the "wall-breaking leader" of light, Saifan Simulator reconstructs the photovoltaic testing logic with "ultimate precision" It covers the full spectrum from 400nm to 1100nm and is equipped with the self-developed 6th generation intelligent spectral fitting algorithm (trained and optimized with 200,000 sets of natural spectral data). The spectral matching degree has exceeded the upper limit of A + level (0.9-1.1). Even the subtle energy fluctuations in the near-infrared band from 780 to 1100nm can be precisely replicated. Make the simulated lighting seamlessly connect with the real sunlight. More importantly, its "ultra-stable output" - a light intensity fluctuation rate of ±0.2% per hour (30% higher than the industry standard), is equivalent to a continuous 24-hour test where the light intensity change does not exceed the "brightness of firefly light emission". The spatial uniformity of ±1.8% ensures that every inch of the battery cell can be evenly "bathed" in light, and the data deviation is strictly locked within 0.8%.
With this "light efficiency weapon", the R&D team of the enterprise identified the core issue in just 15 days: the battery's absorption efficiency in the near-infrared band was 12% lower than expected. By optimizing the material structure, the conversion efficiency of perovskite/silicon tandem cells has exceeded 28.5% at one go. The related achievements have been published in Nature Energy, and the research and development cycle has been shortened by 65% compared with the industry average. In the mass production stage, an intelligent testing production line composed of 12 Saifan simulators completed battery performance testing at A speed of 80 pieces per minute. The A-grade product rate jumped from 86% to 96%, reducing defective product losses by over 25 million yuan annually and rapidly increasing the proportion of high-efficiency battery production capacity of the enterprise to 40%. "Far ahead of the rest" in the photovoltaic technology race.
Aerospace testing: Replicating "Space Environment" with "Extreme Light", making deep space exploration "Full of confidence"
Spacecraft in space have to deal with extremely cold temperatures of -183 ℃, strong radiation, and only 14% of the Earth's light intensity on the lunar surface. Traditional simulators either cannot withstand the low temperatures or the spectra do not match, making the test data simply untrustworthy. The concerns of the chief engineer of a certain academy of China Aerospace Science and Technology Corporation highlight the strictness of aerospace testing. The solar simulator of Saifan Optoelectronics is precisely the "key force" that breaks through the barrier of "extreme light conditions being difficult to reproduce".
The core confidence of Saifan as the "wall-breaking Leader" lies in its "extreme adaptability to all scenarios" : For the lunar exploration mission, the "AM0 Spectrum + ultra-low temperature adaptation" module was developed within 72 hours. It adopts military-grade titanium alloy to strengthen the body and vacuum insulation design. The equipment can operate stably in the extreme temperature range of -200 ℃ to 80℃, with a light intensity fluctuation of no more than ±1.2%, perfectly reproducing the strong radiation and low light environment on the lunar surface. During the continuous 1,000-hour simulation test, the equipment accurately captured the aging pattern of the solar cell wing material of the spacecraft, assisting the team in developing a new type of anti-radiation coating, which extended the in-orbit life of the cell wing by 8 times and provided a "double insurance" for the safety of the power system of the manned lunar landing project.
Facing the special demands of Mars exploration, the Saifan team once again demonstrated its "leading strength" : based on the data of Mars' atmospheric composition, they completed the customization of "spectral filtering algorithm upgrade + infrared band enhancement" within five days, increasing the irradiance in the 800-1100nm band by 35% and precisely restoring the light characteristics of the Mars surface. The solar panels of the Mars rover optimized by this equipment have increased the power generation efficiency by 30% in the weak light environment of Mars, completely solving the "energy sustainability" problem of deep space exploration and making the Mars rover "full of power" on distant planets.
Scientific Research and Agriculture: Unlocking the "Innovation Code" with "Customized Light", Making Cross-border Breakthroughs "Blossom Everywhere"
"We are researching the 'light-controlled rice anti-lodging gene', which requires adjusting the proportion of ultraviolet and blue light at different times every day. Traditional simulators can only output fixed spectra, and the experiment has been stuck for a year without any progress." " The problem of a researcher from a certain institute of Botany of the Chinese Academy of Sciences was easily solved by the Saifan solar simulator. As the "wall-breaking leader" of light, Saifan Simulator, with its "all-dimensional customization" capability, opens up a new window of innovation for scientific research and agriculture.
On the scientific research end, it is a "spectral magician" : the ultraviolet-visible and near-infrared bands support 0.5% precision adjustment, the light intensity can be freely switched from 0.05sun to 3sun, and it can also simulate dynamic lighting scenarios such as solar eclipses, day-night alternations, and seasonal changes, and even output nanosecond-level pulse light. With this capability, the team from the Institute of Botany successfully discovered that 12 hours of exposure to a 450nm blue light band could increase the expression level of rice lodging resistance genes by 200%. The related achievements provide a brand-new direction for the breeding of stress-resistant crops. In the field of photocatalysis, a team from a certain university has increased the efficiency of CO₂ reduction to methanol by 60% through a "UV + near-infrared synergistic illumination" solution customized by the Saifan simulator, providing key support for breakthroughs in carbon neutrality technology.
In the agricultural sector, it has transformed into a "light manager for increasing production" : In a citrus planting base in Taizhou, Zhejiang Province, due to insufficient winter sunlight, the sugar content of the fruits was only 10%, with an average yield of less than 3,000 jin per mu and a selling price of just 3 yuan per jin. The Saifan technical team has customized an intelligent lighting solution of "70% red light + 15% blue light + 5% ultraviolet light" based on the photosynthesis characteristics of citrus fruits, and realizes dynamic adjustment of light intensity and duration through the Internet of Things system. After one growing season, the sugar content of citrus fruits soared to 15%, the yield per mu exceeded 4,000 jin, and the selling price per jin rose to 6 yuan. The 200-mu base increased its annual income by over 1.2 million yuan. Nowadays, "Saifan Customized Light" has become a "prosperity brand" in the local area. More than 50 households in the surrounding areas have followed suit and switched to "light-controlled planting", with an average annual income increase of 80,000 yuan.
Full-cycle escort: With "partner-style service", make "worry-free use of light" the norm
Saifan Optoelectronics is well aware that breaking down the barriers to light requires not only good equipment but also excellent service. For this reason, Saifan has established a "full-cycle partner-style service system" : 10 regional technical centers across the country, equipped with a professional service team of over 50 people, 7× 24-hour online response, arriving at the scene within 4 hours for equipment failure and repairing within 24 hours. For research institutions, regular "Optical Simulation Technology Training Courses" are held, cultivating over 200 professional talents each year to help teams quickly master equipment operation and light efficiency optimization skills. We provide "full life cycle management of equipment" for enterprise customers, conducting on-site performance calibration and consumable inspection every quarter to ensure that the equipment remains in the best operating condition for a long time.
After a certain new energy enterprise introduced the Saifan simulator, the Saifan team not only completed the installation and commissioning but also continuously tracked the production line data. Three months later, they found that there was room for improvement in the testing efficiency. They proactively went to the site to upgrade the algorithm, increasing the testing speed by 15% and boosting the annual output value by 3 million yuan. This "proactive empowerment" service has enabled Saifan to win the deep trust of its customers - the repurchase rate of core customers has reached 90%, and 95% of new customers come from referrals by existing customers, truly achieving a dual guarantee of "technology leadership + service protection".
From the efficient operation of photovoltaic production lines to the safe execution of space missions, from scientific research breakthroughs in laboratories to the joy of bountiful harvests in farmlands, Saifan Optoelectronics' solar simulators have always been like "breaking the wall light", helping various industries break free from the constraints of natural light. When "actively controlling light" becomes the norm, innovation is no longer "trapped by light", and more possibilities for breaking boundaries are constantly emerging under the illumination of this "controllable light". In the future, Saifan will continue to assume the role of a "pioneer in breaking through the walls of light", using more advanced technologies and more considerate services to help more industries achieve leapfrog development in the "new era of light control".
